Motivated by the current requirements of digital 3D museums in the low bandwidth networks, we present a novel and efficient approximation algorithm based on axial symmetry of 3D pottery model. Available simplification algorithms suppress detailed features of the mesh without any change to the rest of 3D model. In this paper, we reduce data for mesh representation while preserving the geometric approximation as well as the model quality of the resulting mesh. First, the main symmetry axis of the pottery model is determined and then main body is detected by slicing parallel planes and separation criteria introduced in our proposed algorithm. Second, actual handles are detected based on sector slicing planes using a robust handle separation scheme. Third, every detected part, i.e. main body and handles, is approximated using a novel circle fitting method. Finally, generated vertices are remeshed and create approximated mesh. Experimental results are presented to illustrate superiority and affectivity of our method. Compared with available mesh simplification algorithms and using the same amount of data to represent the model, the proposed approach gives significant improvement in the accuracy of the approximated 3D potteries.

“…Various methods have been proposed for mesh simplification, and these can be divided into three main categories: vertex decimation, vertex clustering, and iterative edge contraction [5][6][7][8][18][19][20]. Vertex decimation methods involve three major steps: selection of candidate vertexes that satisfy a distance or an angle criterion, removal of loop triangles around the candidate vertexes, and triangulation of the resulting holes [9,18,[20][21][22].…”

“…Although these methods are time-efficient, the candidate vertex selection criterion is based on a local error estimate and therefore cannot guarantee the boundary errors. Moreover, they can only preserve positions, and few salient features are preserved during simplification [7,19,22].…”

“…However, such complex 3D geometric models are not always needed. Due to the limitations in graphics hardware, these models are all difficult to interactively render, calculate, simulate, and analyze [2,3,[5][6][7][8]. In addition to improving the capacity of graphics hardware, it is essential to develop a highly efficient mesh simplification method to avoid excessive details of 3D geometric models [7,[9][10][11][12][13][14][15].…”

To avoid excessive details, thus omitting less important content, of three-dimensional (3D) geometric models, this study proposes a fast mesh simplification method based on an energy-operator for 3D geometric models with salient feature-preserving efficiency. The energy-operator can evaluate the smoothness and complexity of the regional mesh in 3D models. Accordingly, it can be directly used to simultaneously reduce the candidate triangle and its three neighboring triangles. The proposed method can dramatically collapse the excessive details in relatively smooth areas and preserve more important salient features during the simplification process. It can also maintain a trade-off between time efficiency and salient feature-preserving accuracy. The effectiveness and efficiency of the new method are demonstrated by comparing it with OpenMesh, which is considered the most popular mesh operation software and is capable of achieving accurate mesh simplification models. The new mesh simplification method based on the energy-operator can provide accurate and concise models for interactive 3D rendering, calculating, simulating, and analyzing.

International audienceView-dependent surface color of virtual objects can be represented by outgoing radiance of the surface. In this paper we tackle the processing of outgoing radiance stored as a vertex attribute of triangle meshes. Data resulting from an acquisition process can be very large and computationally intensive to render. We show that when reducing the global memory footprint of such acquired objects, smartly reducing the spatial resolution is an effective strategy for overall appearance preservation. Whereas state-of-the-art simplification processes only consider scalar or vectorial attributes , we conversely consider radiance functions defined on the surface for which we derive a metric. For this purpose, several tools are introduced like coherent radiance function interpolation, gradient computation , and distance measurements. Both synthetic and acquired examples illustrate the benefit and the relevance of this radiance-aware simplification process
